Abstract (en)
A method of duplex copying or printing comprises creating a first latent electrostatic image on a dielectric surface of a first image roller (73); toning the first latent electrostatic image to form a toned visible counterpart; transferring the toned first image to a surface of a second image roller (83) in rolling contact with the first image roller (73), this transfer being accomplished solely by pressure; creating a second latent electrostatic image on the dielectric surface of the first image roller (73); toning the second latent electrostatic image to form a toned visible counterpart; passing an image receptor (81) between the first image roller (73) and the second image roller (83); and transferring the toned first image from the second image roller (83) to one side of the image receptor, and simultaneously transferring the toned second image from the first image roller (73) to an opposite side of the image receptor, this step being accomplished solely by pressure with a simultaneous fixing of the toned images to the image receptor.
